On an order book, the spread is what it costs to cross it: the gap between the best price to buy and the best price to sell. A 5.05% spread means the two sides of a typical Opinion Labs market together imply about 105.05% — the cost of trading in and straight back out. It is set by whoever is quoting at that moment, not by Opinion Labs, and it moves with liquidity.
FAQ
- Is Opinion Labs legit?
- Omenizer has not yet verified which company operates Opinion Labs or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 215 Opinion Labs markets in the last 7 days against the rest of the market, so its prices are observable rather than taken on trust. We publish the checks we can evidence and flag the ones we cannot — we do not certify bookmakers.
- Who owns Opinion Labs?
